Imperial Irrigation District Energy offers incentives to residential customers to encourage energy efficiency. This incentive takes the form of rebates offered for qualifying energy efficient appliances and building improvements. Rebates are available on attic insulation, attic fans, room air conditioners, windows, central air conditioning, heat pumps, and pool pumps. Most rebates are offered on a per unit basis, with the exception of central air conditioners, heat pumps and windows, which are based on system size. To be eligible for these rebates, IID residential customers need to mail in a completed application and copies of receipts/invoices. If all criteria have been met, a rebate check will be mailed within 8 - 12 weeks. For more information, consult the program web site.
